Edison Junior, the technology and design lab behind the POP portable power station, is returning the full $139,170 in funding it received from Kickstarter backers to develop the device. Unfortunately, Apple has refused to give the project permission to license the Lightning charger in a device that includes multiple charging options.

“We are pissed,” Edison Junior CEO Jamie Siminoff told me on the phone today. “I think they are being a bunch of assholes, and I think they’re hurting their customers.”
